Power Door Locks (If Equipped) If your vehicle has power door locks, press the power door lock switch to lock or unlock all the doors at once. Programmable Automatic Door Locks Your vehicle is equipped with an auto lock/unlock feature which enables you to program your power door locks. Your vehicle left the factory programmed to have no doors lock and none of the doors unlock. You can set the automatic lock feature to lock all the doors when the vehicle speed is greater than 15 mph (24 km/h) for two seconds, and then unlock the doors you select once the key is removed from the ignition. The following instructions detail how to program your door locks. To enter the program mode you need to do the following: 1. Begin with the ignition in OFF. Then, pull back on the turn signal/multifunction lever all the way toward you and hold it while you perform the next step. 2. Turn your key to ON and OFF twice. Then, with the key in OFF, release the turn signal/multifunction lever. Once you do this, you will hear the lock switch lock and unlock. The power door lock switch will lock or unlock the rear hatch and Dutch doors. See "Hatch Release" in the Index. When a door is locked, the inside door handle will not open the door. This will help stop a door from being accidentally opened. If the sliding door is open and you press the power door lock switch, the sliding door will not lock immediately. After you close the door, the system comes on and locks the sliding door in about five seconds. When the key is in the ignition and the power door lock switch is pressed with a door open, all doors are locked while the driver's side door remains unlocked. 2-9
